ELECTRIC j HEATER.

Specification of Letters Patent.

Patented May 23,1922.

Application led February 1, 1921. Serial No. 441,525.

To all who-m t may concern:

Be it known that I, HENRY KnUnsHnLD, a citizen of the United States,residing at New Viashington, in the county` of, Crawford and State othio, have invented .certain new and useful Improvements in ElectricHeaters, of which the ,tollowingfis a specification.

This invention relates to electric heaters, and has for its particularobject to provide a simple and improved form of heating element, thesame comprising a coil which is supported between two bars of insulatingmaterial, these bars being mounted on a pair of screw rods which can beadjusted to tension the coil and also to attach the element of a base orthe like. Although shown and illustrated .in connection with a stand orupright heater, the element may be used in a horizontal position, or'`on other types of electric heating devices, the main 'feature of noveltycomprising the particular structure of the element itself.

ln the accompanying drawings Fig. l, is a side elevation ot the heatingresistance element, showing the element applied to a stand heater. theheater being in section. Fig. 2 is a longitudinal section of one oftheinsulating bars. y

Reterringspecilically to the drawings, l indicates the bars betweenwhich the heater coil 2 .is `extended in zigzag relation, the coilpassing through holes 9 communicating with groove l0 in each bar. Afterthe coil is set in place this groove or channel may be filled withcement to hold the coil in position. The bars are mounted `at their endson a pair of threaded rods 3 which re ceive nuts 3a between which thebars are clamped, and obviously by adjusting the nuts the bars can beforced away from eachy other to increase or adjust the tension on thecoils 2 so as to support the latter in proper position. The terminals ofthe coils are attached to the ends of the rods 3, where they may befastened by nuts 3".

Fig. l shows one manner ot use ot' the element for a stand heater or thelike, the element being mounted on a base 4L by inserting the ends ofthe rods 3 through holes in the top of the base and clamping the same bynuts thereunder, the cord terminals ll being attached to the lower endsof the rods. The legs 6 of the base may be provided with lihrefeet 7 forinsulation, and a casing l2 may enclose the heating element.

The construction described is very cheap and easily assembled, andprovides an element which can be used for various purposes and which canbe quickly and easily applied to the articles, examples of such articlesbeing stand heaters, toasters and various other heating appliancesfamiliar to those vac-` quainted with the art.

l claim: i

l. A heating element comprising a pair of bars. a coil extending betweenthe bars, and j spacing rods separating the bars, and adapted to tensionthe coil, the ends of the rods being extended beyond one ot the bars andserving to rigidly attach the element to a` support. l j

2. An electric heater comprising a support. having holes therein, a pairof bars of insulating material, `a coil extending back and forth between`the bars, and spacing rods extending between the bars, the ends of therods extending through the holesV and being clamped to the support andprovided with means for attachment of cord terminals thereto.

"In testimony whereof, I do aifix my signature in presence of twowitnesses.
